Rose plant named MacDeepo

ABSTRACT

A new Naples yellow hybrid tea rose variety.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent an unnamed, unpatented seedling of my creation and as pollen parent the rose known as "Mabella" (U.S. Plant Pat. No. 3,228). The denomination of this new rose is "MacDeepo".

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its Naples yellow colored flowers which are attractively displayed against shiny dark green foliage and which are long lasting on the plant and after cutting. Asexual reproduction by budding of the new variety as performed in Clackamas County, Oreg. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "11A" is plate 11A of The Royal Horticultural Society Colour Chart.
